Indian Oil Corporation [IOC] — citi bank indian oil credit card pos not working

Address:

New Delhi, Delhi, 110041

Sir this is a complaint against tyagi petrol pump in west delhi ghevra village. I wanted to redeem my indian oil citi bank rewards points but the person there said very rudely that the machine is not working at first but when i insisted he told me to lock my car and come inside to see if the machine is working or not.
Then i went inside with him, in there was a man calling himself as the manager said he will try to make the machine work but in actual he was busy with his phone and kept me waiting for 10 minutes. His behaviour was very rude and he was least concerned with my problem.
This was the fourth instance in the past one month that there POS machine was not working and the staff is least bothered about it.
Please take some action against the person responsible for this type of harrassment to there customers. I am attaching photo of the written complaint that i made at the gas station
